Benefits of technology

The patent describes a device that can detect a code image in an image and determine the colors of each pixel in the code. It can also convert the colors of pixels around the code into brighter colors to make the code easier to see. The device is useful for identifying and processing images.

Problems solved by technology

When halftone processing is executed to make image data including the code image in which the blur occurs in the edge portion of the element such as a bar recorded on a recording medium, the quality of the code image sometimes deteriorates due to unnecessary generation of dots corresponding to pixels that match the blur.

first modified example

[0057

[0058]The pixel value converting unit 12d may average pixel values of pixels that are intermediate color pixels and are adjacent pixels. Specifically, the pixel value converting unit 12d converts the pixel value of the pixels of interest, which are determined as “Yes” in step S140, and determined as “No” in step S150 into an average pixel value of pixels of interest that are determined as “Yes” in step S140 and are determined as “No” in step S150, at the timing before the HT processing of step S190. Though called as an intermediate color, it does not mean one color, the pixel values of the intermediate color pixels are varied. Therefore, the pixel value converting unit 12d averages the pixel values of pixels that are intermediate color pixels and adjacent pixels, thereby stabilizing the density in the vicinity of the edges of the code elements such as bars in the code image. As a result, the thickness of the code element after HT processing is stabilized, and the sloshing of th...

second modified example

[0059

[0060]When a magnification of pixel number conversion performed by the pixel number converting unit 12a is an integer value, the pixel value converting unit 12d converts the pixel value of the adjacent pixel that is the intermediate color pixel, and the pixel value of the separated pixel that is an intermediate color pixel into the pixel value brighter than the intermediate color, when the magnification of the pixel number conversion performed by the pixel number converting unit 12a is a non-integer value, the pixel value converting unit 12d does not convert the pixel value of the adjacent pixel that is an intermediate color pixel into the pixel value brighter than the intermediate color, and converts the pixel value of the separated pixel that is an intermediate color pixel into the pixel value brighter than the intermediate color.

Abstract

An image processing device includes a code detection unit configured to detect a code image included in the input image, a pixel value determination unit configured to determine whether a pixel value of each pixel included in the code image corresponds to an intermediate color between a color of code elements constituting the code image and a color of a space between the code elements, and a pixel value converting unit configured to convert a pixel value of a separated pixel that is separated from the code elements by k pixels or more, among intermediate color pixels that are pixels determined to correspond to the intermediate color, into a pixel value brighter than the intermediate color, wherein k is an integer of 2 or greater.

Description

[0001]The present application is based on, and claims priority from JP Application Serial Number 2019-208555, filed Nov. 19, 2019, the disclosure of which is hereby incorporated by reference herein in its entirety.BACKGROUND1. Technical Field[0002]The present disclosure relates to an image processing device, an image processing method, and a recording device.2. Related Art[0003]It is disclosed that an image processing device performs, when the information of the barcode image is included in the image data for forming an image by an image forming unit, and when either of the resolution of the image forming unit and the resolution of the image data is not integer multiple of the other, regarding the resolution of the image data at the location of a barcode image as a resolution that one is an integer multiple of the other, and outputting to the image forming unit (See JP-A-2016-64511).[0004]When a draft on which a code image such as a barcode and a two-dimensional code (QR code (regis...
